theVisualMD: A New Way to See Your Health – What is Asthma?
Get on board a flight into your own airways. You’ll go where asthma happens, into the bronchi of your lungs. Experience the flow of air into and out of your lungs and listen as asthma experts explain how that airflow can be blocked. Zoom in closer to see what airways obstructed by cells of the immune system and mucus look like. View the muscles that wrap around the bronchi to understand how they can cut off airflow when they constrict. See how different inhalers are used, and take a close-up look at some of the microscopic allergens that can trigger an asthma attack. View pulmonary function testing and learn how to keep track of your own air flow—and how keeping it under control makes all the difference.
